SY0-501 Question #340: Real Exam Question with Answer & Explanation

Question

A company is developing a new system that will unlock a computer automatically when an authorized user sits in front of it, and then lock the computer when the user leaves. The user does not have to perform any action for this process to occur. Which of the following technologies provides this capability?

Options

• AFacial recognition
• BFingerprint scanner
• CMotion detector
• DSmart cards

Explanation

This question identifies the biometric technology capable of automatically unlocking a computer upon an authorized user's arrival and locking it upon their departure, without requiring any manual user action.

Common mistakes.

• B. A fingerprint scanner requires a user to actively place their finger on the sensor, which constitutes a user action and does not enable passive automatic locking or unlocking.
• C. A motion detector can sense general movement but cannot identify a specific authorized user, thus it cannot provide secure, personalized automatic unlocking or locking.
• D. Smart cards require a user to physically insert or tap the card into a reader, which is an explicit user action and not an automatic, passive process.
